IDEA多线程下多个线程切换断点运行调试的技巧

多线程调试设置可以参考：http://www.cnblogs.com/leodaxin/p/7710630.html

 

1 断点设置如图：

 

 

2 测试代码，然后进行debug

package com.daxin;
import java.util.HashMap;
/**


Created by Daxin on 2017/10/22.

*/

public class HashMapInfiniteLoop {

private static HashMap<Integer, Integer> map = new HashMap<Integer, Integer>(2, 0.75f);
public static void main(String[] args) throws InterruptedException {

map.put(5, 55);
new Thread("Thread1-Name") {

public void run() {

System.out.println("Thread1-Name Start");

try {

Thread.sleep(5000);

} catch (InterruptedException e) {

e.printStackTrace();

}

map.put(7, 77);//断点位置 1

                System.out.println(map);

}
}.start();

new Thread("Thread2-Name") {
public void run() {

try {

System.out.println("Thread2-Name Start");

Thread.sleep(5000);

} catch (InterruptedException e) {

e.printStackTrace();

}

map.put(3, 33);// 断点位置2

                System.out.println(map);

}
}.start();
// 断点位置 3

System.out.println("Thread-Main-Name Start");

System.out.println("Thread-Main-Name Start");

System.out.println("Thread-Main-Name Start");
Thread.sleep(500000);
}

}

 

3：启动debug，我们可以在Threads Tab选项双击需要进行单步调试的线程

然后选择Frames Tab选项中调试的线程进行快捷键调试即可。
